Frequently asked questions
What is a healthy BMI?
WHO adult ranges: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30+ obesity. These ranges do not apply well to children, pregnant people, or some athletes.
Is BMI accurate?
BMI ignores muscle, bone density, fat distribution, ethnicity and age. Treat it as a rough population screening tool, not a personal health assessment.
Is this medical advice?
No. Qivora does not provide medical advice. Talk to a clinician about weight, nutrition or health concerns.
